What is the difference between horticultural LED and classic LED?
   

The main difference, and it's fundamental, lies in the light spectrum. A classic LED is designed for human lighting, with a broad spectrum but often not optimized for photosynthesis. A horticultural LED, on the other hand, is specifically calibrated to provide the precise wavelengths (blue, red, green, UV, IR) that plants need for their growth and flowering. This is what makes all the difference in indoor cultivation.

What is a 400W horticultural LED lamp used for?
   

A 400W horticultural LED lamp is designed to effectively replace natural sunlight in an indoor growing environment. It provides the light energy necessary for photosynthesis of your plants, from germination to flowering. In practice, it ensures vigorous growth, abundant flowering, and quality production, all with controlled electrical consumption compared to older technologies like HPS.

How far should a 400W LED be installed from plants?
   

The ideal distance for a 400W LED depends on several factors, including the specific lamp model and the growth stage of your plants. In general, I recommend starting with a distance of approximately 40 to 60 cm during vegetative growth, then gradually reducing it to 30-45 cm during flowering. It is crucial to observe your plants: if the leaves yellow or burn, the lamp is too close; if they stretch, it is too far. Some manufacturers provide precise recommendations, you should always refer to them.

What light spectrum for a 400W horticultural LED?
   

For a 400W horticultural LED, I prefer a full spectrum. This means it must include a good proportion of blue (for vegetative growth), red (essential for flowering and fruiting), but also green, UV, and IR. Green, for example, penetrates deeper into the canopy. A balanced spectrum ensures that your plants receive all the necessary wavelengths at each stage of their development, thus maximizing their potential.

Is a 400W LED suitable for autoflowering plants?
   

Absolutely, a 400W LED is perfectly suited for growing autoflowering plants. Thanks to its full spectrum and power, it can provide the constant and high light intensity that autoflowers need throughout their cycle, often under an 18/6 or 20/4 light regimen. The efficiency of LEDs optimizes the growth and yield of these varieties without the thermal constraints of older technologies. It's an excellent choice.

What mistakes should be avoided with a 400W horticultural LED lamp?
   

With a 400W horticultural LED lamp, there are a few classic mistakes to avoid. The first is not respecting the correct distance from the plants, which can lead to burns or stretching. Then, poor ventilation management can create hot spots, even if LEDs heat up less than HPS. I often see growers neglecting the quality of water and nutrients, thinking that light is enough. Finally, not adapting the light cycle to the plant's stage is a common mistake. Also consider the quality of your equipment, as I explain in this comparative article.
